Abstract: Hubbs (1952) introduced the term "antitropical distribution"
in reference to species found north and south of the tropical zone but not in
the tropics. To this may be added the term "antiequatorial distribution" for
those animals and plants that occur south of the Tropic of Cancer and north
of the Tropic of Capricorn but not within the equatorial latitudes. The following
species of Indo-West-Pacific fishes not mentioned by Hubbs (1952) exhibit
antitropical or antiequatorial distribution. Sphyraena zygaena, Cirrhigaleus
barbifer, Meadia abyssalis, Lycodontis eurostus, Diaphus brachycephalus, Lepadichthys
frenatus, Adioryx furcatus, Myripristis chryseres, Ostichthys archiepiscopus,
O. oligolepis, Zenopsis nebulosa, Neosebastes entaxis, Aploactes
aspera, Plectranthias kelloggi, Aulacocephalus temmincki, Amblycirrhitus
unimacula, Cirrhitops fasciatus, Cheilodactylus vittatus, Trachurus novaezelandiae,
Pseudocaranx dentex, Carangoides equula, Erythrocles schlegeli,
Pristipomoides auricilla, Randallichthysfilamentosus, Pentapodus nagasakiensis,
Pentaceros richardsoni, Histiopterus acutirostris, Microcanthus strigatus, Chromis
chrysura, C. flavomaculata, Chrysiptera starcki, C. tricinctus, Bodianus
vulpinus, B. perditio, B. leucostictus, B. izuensis, B. tanyokidus, Choerodon
fasciatus, Novaculichthys woodi, Coris picta, Pseudojuloides elongatus,
Suezichthys gracilis, Limnichthys fasciatus, Entomacrodus niuafoouensis,
Kelloggella oligolepis, Psilogobius mainlandi, Coradion altivelis, Hemitaurichthys
thompsoni, Genicanthus watanabei, Centropyge interruptus, Acanthurus leucopareius,
Xanthichthys mento, X. lineopunctatus, Thamnaconus modestoides,
T. hypargyreus, and Arothronfirmamentum. It is expected that other examples
of this discontinuous north-south distribution will be revealed, particularly
when systematic studies are completed for some groups of Indo-Pacific fishes
in need of revision. Further collecting in tropical areas will undoubtedly
invalidate some of the examples listed above as antitropical.
